Definitions

  • the present invention is with respect to fiber cans of the sort having a multilayer or laminated body with a fusible gas-tight lining, an end wall shutting off a first end of the body, and a partly metallic cover that is made up of a rigid cover member.
  • the cover member is crimped on a second end of the body and has an opening shut off by a covering diaphragm, which is fixed in place by adhesive bonding or by heat sealing.
  • One purpose or object of invention is that of improving the fluid-tightness of fiber cans of the sort in question.
  • a further aim of the invention is to make possible a gas-tight form of such a fiber can.
  • the cover member has a fusible coating on its inner side, such coating having an affinity for the lining of the body and being thermally sealed to the said lining of the body when the cover member is fixed in place, and furthermore the covering diaphragm is so elastic or is so preformed that any pressure differences between the inside of the can and outside coming into existence after the closing of the can are responsible for changes in the form of the diaphragm; or in other words the diaphragm keeps up with and makes allowances for such pressure differences by changing its shape.
  • the lower end wall of the can is in the form of a metal plate with a crimped edge and on its inner side it has a coating with an affinity towards the lining of the can body, such coating being thermally sealed or welded to the lining of the body when the end wall is crimped onto the body.
  • the can body may be made of one paper or cardboard layer or a laminate thereof, the inner layer of the body having the lining thereon.
  • Such fiber cans with this form of body may be produced at a low price.
  • the body is best made by longitudinally winding the material, there being a lengthways seam running along a line on the outer face of the structure parallel to the axis of the can body.
  • a can body produced in this way has the edge over a spirally coiled body inasfar as the seam is straight, is regularly positioned and is only completed after the body has been formed.
  • the seam is shorter and cheaper to produce than in the case of a spirally coiled body, that furthermore has to be seamed along a spiral line while the body is in the process of being shaped.
  • a lengthways coiled or wound can may be welded because of the regular, straight seam to give a safe and gas-tight join without the seam being acted upon by any more deforming forces.
  • gas-tight forms of fiber cans may be produced that have an other than round cross section.
  • the cover part is designed in the form of a ring and the covering diaphragm is fixed on a tear-open tab by which the fiber can may be opened to get at the filling in it.
  • the tab may be joined with the outer limit of the covering diaphragm or if it is only to be opened over part of its cross section it may be joined with the diaphragm by frangible connection points.
  • the design may be such that the opening is placed eccentrically in the cover member for functioning as a filling and/or drinking opening and the covering diaphragm is formed by a tear-off tab covering over the opening.
  • This form of the invention is more specially suitable for liquid products such as beverages or the like, and more specially for those beverages that are stored under a gage pressure, as for example carbonated beverages.
  • the tear-open tab forming the covering diaphragm has a smaller free cross section than the other form of the invention so far noted, but however it may give away to changes in pressure within the necessary limits.
  • the lining of the cover member is drawn like a film over the opening and the tear-open tab with the inner coating thereon is welded or heat-sealed thereonto.
  • the inner coating on the cover member may be produced thereon after the opening has been stamped therein.
  • the inner coating on the cover member and the inner coating of the tear-open tab are placed on top of one another so that they may be joined together partly or over their full surfaces by heat sealing.
  • the inner coating on the cover member covers over the edge of the opening so that same is guarded against the access of the product and there is no chance of interaction between the material of the cover member and the product.
  • the cover member is only made in the form of a ring, it will by the nature of things have a large middle opening, that is covered over by the covering diaphragm, it is best for the inner coating on the cover member to be pulled over the edge of its opening as far as the outside, whereas the covering diaphragm has a fusible coating, having the desired type of affinity, and is heat sealed to the cover member.
  • an outer coating having an affinity for the coating on the cover member and the lower wall, such coating being heat sealed to the inner lining of the cover and end wall, when the cover member and the lower wall are fixed in place on the body.
  • This form of the invention is responsible for an even larger heat sealing surface at the closure so that it is made even more highly gas-tight.
  • FIG. 1 is a broken away lengthways section through a first form of fiber can in keeping with the invention.
  • FIG. 2 is a section, on the same lines as in FIG. 1, of a second working example of the present invention.
  • the fiber can 1 or container to be seen in FIGS. 1 and 2 has a can body portion 2, that is made of paper or cardboard laminate which if needed will have a sealing or barrier layer included therein in the form of metal foil.
  • the can body is more specially produced by a lengthways winding operation so that the body 2 is completed by a lengthways seam 3 (see FIG. 2) running along the outer face of the said body parallel to the axis thereof.
  • the said body 2 has a lining 4 of plastic with the desired properties to adhere to food and drugs legislation, such lining at the same time forming a gas- and liquid-tight barrier or sealing layer for guarding the multilayer or laminated can body 2.
  • the lining 4 is sealed or thermally welded along the lengthwise seam 3 after the body has been produced.
  • the fiber can 1 is shut off by an end wall 5 and the opposite end is shut off by a cover 6.
  • the lower end wall 5 is in the form of a deep drawn metal plate with a crimp-on edge 7. Furthermore the lower end wall 5 has a coating 8 on its inner face of a plastic having an affinity for the lining 4 of the can body 2.
  • the deep drawn metal plate is placed on the open end of the can body 2 and joined therewith by crimping down the edge 7 on the end of the body 2.
  • the lining 4 of the can body 2 and the inner layer 8 of the lower end wall 5 are heat sealed to each other.
  • the cover 6 has a rigid cover member 9 in the form of a cover ring with a crimp-on edge or peripheral crimping lip 17 running round it.
  • the ring-like cover member 9 has an inner coating 10, that is for its part made of a plastic having an affinity for the lining 4 of the can body 2.
  • the rigid cover member 9 has an opening 11 with a relatively large cross section with a covering diaphragm 12 stretching over it.
  • the covering diaphragm 12 is best made of a metal foil 13, that for its part has a plastic coating 14.
  • the covering diaphragm 12 is in this form of the invention fitted with a tear-open tab 15 formed on the covering diaphragm 12, for example by forming cuts in a stamping operation.
  • the crimp-down edge or peripheral crimping lip 17 is crimped round in the same way as is the case with the end wall 5 on to the end edge of the can body 2 and the coatings 4 and 10 are heat sealed together.
  • the inner coating 14 of the covering diaphragm 12 is heat sealed to the outer coating 10 of the cover member 9.
  • the cover diaphragm 12 is made with such elastic properties or is so slightly preformed that it may give way under the effect of vacuum or gage pressure as produced after filling the can, this being marked in dashed lines.
  • the sealed fiber can 1 is opened by pulling on the tear-open tab 15, the can then being opened over its full cross section 11 so that the product may be poured out or taken therefrom in some other way.
  • FIG. 2 there is a different form of the cover 6. It has a cover member 9, that has a small eccentric filling or drinking opening 16.
  • the rigid cover member 9 again has its inner coating 10 and a crimp-on edge 17.
  • the cover member 9 is fixed onto the can body 2 in the same way as with the working example to be seen in FIG. 1.
  • a change is present here inasfar as the opening 16 is covered up by a covering diaphragm 18 in the form of a tear-open tab 19.
  • the covering diaphragm 18 has an inner coating 20 made of a plastic with an affinity for the inner coating 10 of the cover member.
  • the coating 10 is in this form of the invention drawn like as sort of film over the opening 16 in the part 21 so that the edge of the opening of the cover member 9 is covered over thereby.
  • the inner coating 20 of the covering diaphragm 18 and the film-like part 21 of the inner coating 10 on the cover member are placed right against each other so that they may be quite simply heat sealed or welded to each other.
